Wire fixing device for pacemaker electrode

Abstract

The present invention relates to a wire fixing device for a cardiac pacemaker electrode, including: an electrode fixator used for clamping the tail of an electrode, where the electrode fixator includes an electrode clamping component, first hooks and second hooks; the electrode clamping component includes a first clamping piece and a second clamping piece that are semicircular cylindrical, one side edge of the first clamping piece and one side edge of the second clamping piece are connected in a hinged manner by a clamp hinge connector, and a circular tube is formed when the electrode clamping component is closed; several first hooks are provided on the back of the first clamping piece, several second hooks are provided on the back of the second clamping piece, and hook tips of the first hooks and the second hooks are all bent towards a rotation direction of the electrode clamping component during closing; and the first hooks and the second hooks can be interlaced with each other when the electrode clamping component is closed, and can be separated when the electrode clamping component is open. The present invention does not require a suture, achieves firm fixing, does not damage an electrode, and facilitates detachment and re-implantation.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of China application no. 201710156356.8, filed on Mar. 16, 2017. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUNDTechnical Field of the Present Invention[0002]The present invention relates to a wire fixing device for pacemaker electrode, belonging to the technical field of medical instruments.Technical Background of the Present Invention[0003]Currently, after implantation of a pacemaker and an electrode, the electrode is mainly fixed by using a suture. Fixing the electrode with a suture has the following disadvantages: 1. it is time and labor consuming; 2. the suture slips easily and the electrode may shift; 3. an excessively tight ligation may damage the electrode; 4. it is even more time and labor consuming to remove the suture and stitch again if the electrode needs to be moved.SUMMARY OF THE INV...

AI Technical Summary

Benefits of technology

The present invention provides a wire fixing device for pacemaker electrode that is not requiring a suture, achieves firm fixing, doesn't damage the electrode, and facilitates detachment and re-implantation. The invention is designed to overcome the defects of the prior art. Compared to the prior art, the invention has the advantages of being ingenious in structure and reasonable in design. It only requires two clipping actions to achieve film fixing and does not damage the electrode. These technical effects make the invention effective in achieving its goal of providing a safer and more efficient wire fixing device for pacemakers.
